I have a Case DX33 which is essentially a red TC33DA.
Dual remotes. Well worth it. It'll take a long afternoon for the installation, but well worth it.
One tip, I haven't checked recently, but the Single was like $500 or something when I bought the kit and the dual was $650 is all or something. I remember the price difference between one and two was small enough that I thought, "duh....get two...." I'll look a bit later and see what I can find for you....
